how can i store matrix inside simulation to get bigger matrix ?

i'm creating a simulation and first step result is matrix for example matrix of order (100 row and 4 columnes) the simulation next step must be in same orde , i want to make a storage to save the matrix of order (200 rows and 4 columnes) and so on i used the following code z(i,:)=horzcat(samples) note samples is the matrix that has resulted in the first step the code i used didn't work what can i do?

Please post the relevant part of the code. It is impossible to guess, what your "i", "z" and "samples" exactly are. In addition "didn't work" does not allow to suggest an improvement. Better post the error message or explain the different between the results and your expectations, respectively.

z=[];
%first result
A=rand(5,4);
z=[z;A];
%second result
A=rand(5,4);
z=[z;A]
% and so on
